True, but then again you could say that Christmas is weird to celebrate because Jesus Christ isn't born every year, they say it happened a long time ago. Same thing with Easter, Thanksgiving, etc...
How true. Commemorations, celebrations, thanksgivings should be done every single moment of one's life that one is alive, well and kicking.
But in anycase, Happy Independence Day to all the US Americans. Without that historical event, you wouldn't be what you are now.
